Driver Facial Image Position Tracking Icon Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging state confirmation devices struggle to accurately adjust the position of a driver's face within the imaging range of a camera, especially when the driver's seating position or the camera's orientation needs to be adjusted, leading to difficulties in maintaining a proper imaging state.
Innovation Solution
The proposed imaging state confirmation device includes a position detection unit to track the driver's facial image, an icon display unit to visually represent the facial image position, and a positional change display unit to adjust the icon's position based on seat or camera adjustments, ensuring the facial image remains properly aligned.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the position of the seat or the orientation of the camera is adjusted to correct the facial image position, then the imaging state can be improved, but the facial image position may move during the adjustment operation, making it difficult to complete the adjustment
Solution Approach 1:
The patent implements a feedback mechanism by displaying an icon that represents the facial image position on the screen. This icon moves in response to seat or camera adjustments, providing real-time visual feedback to the operator. The feedback loop allows the operator to see the effect of each adjustment and make precise corrections without guessing, thereby resolving the contradiction between improving imaging accuracy and maintaining ease of operation.
Solution Approach 2:
The patent introduces an intermediary element - the icon - that mediates between the physical adjustment operations and the imaging state. Instead of directly manipulating the camera or seat without visual reference, the operator interacts with the icon on the display, which translates physical adjustments into visual position changes. This intermediary provides a stable reference point during adjustment operations.
2Loss of information
If real-time imaging is performed during seat or camera adjustment, then the imaging state can be monitored, but the facial image position changes during adjustment, making it difficult to determine the correct position
Solution Approach 1:
The patent creates a copy of the facial image position information in the form of an icon displayed on the screen. This icon is a visual representation that copies the position information of the facial image without being affected by the physical movement during adjustment. The icon provides a stable, accurate reference that maintains its correspondence to the correct facial image position even when the actual imaging is undergoing adjustment.
Solution Approach 2:
The patent performs preliminary action by establishing the icon's position before and during adjustment operations. The icon is initially positioned to represent the facial image position, and then it is updated to reflect changes as adjustments are made. This preliminary establishment of a reference system allows the operator to understand the current imaging state at any point during the adjustment process.

AI summary
An imaging state confirmation device for confirming an imaging state by an imaging device that images an image of a driver includes a position detection unit that detects a position of a facial image of the driver in an image imaged by the imaging device at an arbitrary point in time, an icon display unit that displays an icon in an arbitrary frame of the display device so as to correspond to a position of a facial image in the image, and a positional change display unit that changes a position of an icon in the frame of the display device and displays the icon based on an adjustment amount of a state of a seat on which the driver is seated or an adjustment amount of a state of the imaging device.
